Phase morphology and melt viscoelastic properties in blends of ethylene/vinyl acetate copolymer and metallocene-catalysed linear polyethylene

Effect of PE-g-MA compatibilizer on the structure and performance of HDPE/EVA blend membranes fabricated via TIPS method

“…Blends of HDPE and EVA are a new class of thermoplastic elastomers, which couple the superior properties of HDPE and EVA and open up new avenues for the commercial use of these blends (John et al, 2011). The mechanical, rheological and thermal properties of PE and EVA blend polymers have been well studied (Ray and Khastgir, 1993;Poen et al, 2003;Khonakdar et al, 2004;John et al, 2010). Although the advantage of the use of polymer blend in the TIPS process is that pore size can be controlled by the addition of second polymer due to changes in thermodynamics and kinetic properties (Fu et al, 2006), however, there are very few reports regarding the application of PE/EVA blend polymers in fabrication of membrane.…”

Effect of composition on the linear viscoelastic behavior and morphology of PMMA/PS and PMMA/PP blends

“…It is inversely proportional to interfacial tension and proportional to R. The identification of a third relaxation time in the relaxation spectrum of the blend can therefore enable the evaluation of interfacial or blend morphology. Some studies have shown that there might be an influence of blend composition on the determination of interfacial tension between the components of the blend using dynamic data [11][12][13][14][15][16]. Lacroix et al [11] observed that the values of interfacial tension obtained fitting Palierne's model to linear viscoelastic data of blends of polyethylene terephthalate copolymer(PETG)/ethylene vinyl acetate (EVA) depended on blend composition.…”

Crystallization of partially miscible linear low-density polyethylene/poly(ethylene-co-vinylacetate) blends

“…In the meanwhile, the introduction of ester groups into the blends can also provide better miscibility with inorganic fillers. Recently, metallocene linear low-density polyethylene (m-LLDPE)/EVA blends has attracted great interest [18][19][20][21][22]. Peon et al [18] and Moly et al [19] reported the immiscibility of m-LLDPE and EVA (VA content of 27 or 18 wt.%).…”

Peon et al [18] and Moly et al [19] reported the immiscibility of m-LLDPE and EVA (VA content of 27 or 18 wt.%). Wu et al [20] suggested that m-LLDPE and EVA (VA content of 14 wt.%) showed the miscibility and co-crystallization at lower EVA content.…”
